Truman threatened this indirectly in 1946 when the Russians refuesed to leave Iran. He was successful. The Soviets left.
Yeah, while Bush is watching the frisbee competition between the Congo and Mongolians, he should start issuing threats to Russia.
Uhm no. He should return and THEN issue threats. Bush should return ASAP to the US (or if he is a daredevil better to Tiflis) and declare full US support to Georgia, or at least give a dire warning to the Russians. A Pandora’s box is being opened in the Caucasus.
